To Ann WHoM AIr MAY vooNeERr:

Be it known that-I, JOHN NATION, of Portland,l Multnomah county, Oregon, have invented a new and useful Mode of Injectinp,r Oil or Tallow into Steam-Cylinder Chests and Steam-Cylinders for Lubricating Purposes; and I do hereby declare that the following is a'full, clear, and exact description thereof, which will enable others l skilled in the lart lto mali@ and use the same, reference being had to the accompanying drawings, forming part of' this specification.

My invention consists in admitting oil or tallcw into a proper receptacle, and in applying'steam to force theoil or tallon into the steam-cylinder chest or steam-cylinder. In the accompanying sheet of drawings-e- Vvalve'DX, upper seat'H,' and slotted lower seat E, as herein described.

igure l'is a vertical centrahsection of my invention. Fgur'efra horizontal section of the same, taken in the line :c 9:, fig. 1. Silhilarletters of reference indicate'corresponding parts. y Alv'iepresents-a cup, in which the oil or tallow is placed, and B `a cock, which, when opened, allows the oil or tallp'vi'lfo ow into cylinder C through the passage a. 'D is a cock, applied to the cylinder C to'serve as a4 venti said cock, when open, allowing the air to escape from cylinder C as the oil or tallow flows into it. At the Bottoni of the cylinder C there is a valve, DX, closing` upward against a seat, H, and it is corrugated at its outer'edge, as shown ntl), to admit of the dow of oil or tallcw from cylinder C. This valve, DX, when forced down and opened by the pressure of steam in C,.rests upon -a slotted perforated seat,'E, through which the oil or tallcw pnsse'siroin C into steam-cylinder' chest F. G repres'ents a steam-pipe, provided with a cock, c. This pipe communicates with 'the cylinder C and the steam-cylinder chest F, to admit steam into C when necessary.- l i The operation is as follows: .T he oil or tallow is placed in the cup A, the latter being always kept supplied with it.;` that, atleast, would be'preferable. ,The cock Dis opened, and also the cockB, and the oil or tallow-ows from A intoleylinder'CJ; The cocks D Bare then closed, and thesteam-cock c opened., and the pressure ofthe steam on the oil and tallow will force the same downward, and also the valve DX, the latter resting on the slotted perforated seat E, and the oil and tallow passing down'through 'the corrugated edge of DX, and thc slotted perfrated seat E,nto the` steam-cylinder -chest F. By turning the steam-cock c, so as to shut ofi' the' steam from C, the pressure of the steam inA F will raisel the valve DX against the upper seat H, and close the commu-f nication between C andF, D being opened, if necessary, for ste-ain to exhaust-from C;

Having thus described my invention, what I claimias new, and desire to secure by Letters Patent, is-

1. Thevalve DX, having corrugatious'b, the slotted'seat E, constructed and arranged to o'perate as herein described. .A

2. The arrangement of the oil-cup A.wit-h the cocks B D, cylinder C, steam-pipe G, cock c, corrugated JOHN NATION.
